Meragura Volcano (Japanese: メラグラー火山 Meragurā Volcano) is a location exclusive to the Pokémon Try Adventure manga.
Katsuya, Soro, Toki, and Caty visit Meragura Volcano as part of their mission from Mister Crow. A group of Grass and Bug-type Pokémon led by Tangrowth attacked. Katsuya and his friends managed to defeat them and Soro caught Tangrowth. When they went inside, they meet a Heatran who was the guardian of it and an Entei. The group separated and Soro managed to capture the Entei after he was rescued from an attacking Onix. The group rejoined each other and found out that the volcano was about to erupt. They work together to make a hole in the ceiling so the volcano could properly erupt.
